1 Claim.

This invention relates-to-folding boxes or'cartons of foldablesheet'material such aspaperboard and which are formed fromintegral-blanks. particularly it aimsto'provide a polygonal device ofthe class described for use as a dispensing holder or package especiallyfor rolls of waxed or other paper, foil and the like sheets, and'toprovide a one-piece blank 'for such'polygonal and particularly hexagonalboxpeculiarily adapted for setting up on machines as known under thetrade-mark Brightwood.

In the drawings illustrating by way of example one embodiment of theinvention:

Fig. 1 is a perspective View of a dispensing box of'the invention inset-up but open condition;

Figs. 2, 3 and 4 aresectional views on a transverse plane and lookingtoward the inner face of one end of the set-up box as indicated by thesection line on Fig. 1, showing the same in successive stages ofclosure;

Fig. 5 shows a blank for the'box; and" Fig. 6 is anenlarged detail of anupper corner portion of the closedbox; as at theleftin Fig. .1.

Referring now tothe drawings in more detail and first to Fig. 5, theone-piece paperboard or like blank as there shown is -generallyrectangular and comprises a series of integrally united longi tudinalside panels appropriate in number for theformation'of the bodyof'apolygonal box, herein illustrated as hexagonalr- While astoisome aspectsof the invention the-boxmayrbeprovided with a greater or lessernumberlof sidesth'an six the constructioniand arrangement asillustrated. is especially adapted:.tormulthpolygonal forms; wherein aloosely. insertedsheetmoll such as-Pt,

Fig. 4, will have. at. the lowerrportiomthereof at least threelongitudinal wallshin: approximate" tangential relation-to it.

The several side panelsof .the. box blank will forv convenience. bevidentified with referenceto their. position. in theseteup box.. Theyinclude. a top. side. or. hinged cover member ll,-.an .upper back. sideII. a lower. back. side..l2',.a bottom. side. or.

floor 3, a lower front side It and anupper front side I 5 which hereinalso. constitutes a hinged cover. member. These longitudinal panels,numbered in the order. from top to bottom in Fig 5,

are demarkedibylongitudinal and herein parallel scored or otherfoldlines a, b, c, d, .e, and 7 respectively between each two adjacentpanels and upon which'the blankisfoldable'insetting up the box. Thescorelinea along the outer edge of the top side ill constitutes a hingeline between the latter and. a longitudinal tuck flap lfi' carried bysaid top-side and defining one longitudinal" margin 0f'the=b1ank.

The top side or cover panel 10 and the tuck flap I6 thereof havefreeedges at the opposite ends. The side panels Il-i5 each have endextensions, to be referred to, the panels proper be r conform to and toclose the ends of the tubular box body provided by the side panels lill5in the set-up state. Asshown said end panels I8 are polygons with asmany side edges as there are sides for the box. In the illustrated sixsided example they'are hexagonal. In a dispensing roll holder with whichthe invention is mainly but not exclusively concerned the box sidespreferably are of equal width or substantially so. The end panels itaccordingly are shown as equilateral hexagons.

The blank is further formed to provide dust flaps is on the end panelsI8. These are shown as quadrilateralextension opposite thebottomconnected' sides 9' of the end panels and dc marked from them byscore lines 71. These dust flaps is each have a longitudinal edge-withlateral projection l9c substantially in line with the front hinge line eof the bottom panel l3. In the set-up closed box'the dust flaps l 9 areturned in and lie closely parallel to the top cover 19, Fig.

flap [5- thereof. For convenience in closure the sides of the dust flapsopposite the front edges 19a are inclined toward the latter and theouter end edges substantially parallel the hinges h, giving the dustflaps herein a trapezoidal shape.

Referring again to Fig. 5 and the blank thereof, a plurality of the sidepanels, herein. the lower back panel I2; the upper back panel II and thelower front panel id; have extensions at both ends of the blank thereproviding glue flaps 20, 2| andZZ; These are so shaped and proportionedthat'together they present a total area approach ing that of thecorresponding end panel 18.

In setting upthe box the glue flaps at each end are turned into a commontransverse plane so as to be received fiatwise againstthelll!li"'f2l-CE0f' the cor esponding endpanel l8,

' or? which they overlap substantially rnore than halfthe area. In theillustrated example the total glue flap area is approximately of eachhexagonal end panel. As seen in Fig. 2 the described glue flaps 28, 2|,22 overlap substantially the entire upper half of the adjacent end paneli8 and considerably more than one-half of the lower half of the latter,approximately of such lower half in the illustrated instance.

This is accomplished by forming the several glue flaps as sectors andcombinations of sectors and half-sectors of the hexagonal end walls l3.In the illustrated example the glue flap on the lower back panel I2 isof substantially equilateral triangular form, equivalent in area to oneonesixth sector of the end walls. The adjacent glue flap 2| on the upperback panel H is a trapezoidal quadrilateral of approximately 1 /2 timesthe area of glue flap 20, that is, equivalent to one and one-half endwall sectors. The glue flap 22 on the lower front panel !4 is ofpentagonal form with an area equalling that of the glue flaps 20 and 2|together, equivalent to two and one-half end wall sectors. Accordinglythe three glue flaps 29, 2| and 22 will together overlaps the entiretyof the corresponding end panel l8 save for the sector immediatelyadjacent the hinged bottom edge g thereof. At that region adequatestrength and rigidity is inherent from the integral relation of the endpanels to the blank as a whole.

The described end panels I8 and the several glue flaps 2s, 2 I, 22occupy the opposite end edges of the bottom panel IS, the lower back andfront panels i2 and I4 and the upper back panel H. In the set-up andsecured position with the glue flaps adhesively or otherwise secured inface contact at the inner faces of the end panels It said fourlongitudinal panels H to It are held in relatively fixed non-openingrelation.

Among the advantages for the hexagonal sideopening box of the inventionis the capacity to 1 be handled in commercial box machines such as thoseof the Brightwood type. This is largely by reason of the fact that theglue flaps 2|, 2%, 22 at the respective sides of the blank are in lineand accordingly may readily have glue applied to them during travelthrough the machine in the direction perpendicular to the side panels,that is, from top to bottom or the reverse as viewing the blank in Fig.5. If the face of the blank as seen in Fig. 5 is regarded as the insideit will be understood that the glue is applied upon the underface of theglue flaps 28-42 as the blanks pass through the gluing mechanism of theBrightwood machine.

As previously noted the hinged top panel ill and its tuck flap [8 defineone longitudinal margin of the blank and are free of end projections.The opposite longitudinal side of the blank is defined by the upperfront side and cover panel Hi. This is hingedly connected at the scoreline along the adjacent side of the lower front panel M. The respectiveend edges of this front upper side cover element are each formed with aherein quadrilateral tuck tab 23 hinged along the score or fold line gand projecting longitudinally and angularly. The outer longitudinaledges 23a of these tuck tabs are disposed at such angle to the freelongitudinal margin |5a of the openable upper front panel IE on whichthey are carried that in the set-up and closed condition, as seen inFigs. 3 and l, the tab edge 23a will coincide with the plane of theopenable top H].

The tuck tabs 23 of the upper front panel I5 are non-glued, contrastingin this respect to the glue flaps 20, 2|, 22 and are free to contributeto an interlocking relation of the parts in the completely closedposition of the box, Fig. 4. Thus the upper front side panel 15 isconstituted as an openable folding hinge cover element equally with thecooperating openable top cover element to at the opposite longitudinalside of the blank. It will be understood that the terms such as top,bottom, upper and lower are herein used for identification and withoutnecessary limitation as to the use position oi the dispenser box. Thesix panels it to It all constitute longitudinal side walls for the box,and the two terminal side walls to and $5 at the opposite longitudinalmargins of the blank, adapted to meet along their opposed longitudinalside edges when the box is closed, together constitute openable sidewall means having oppositely hinging portions connected to respectivelyadjacent fixed side walls It and I4. Thus the box is readily openable toreceive a roll R which may initially have a diameter greater than thewidth of any one of the side walls of the box. In Fig. 4 the contentroll R shown dotted is assumed as having been partly dispensed and henceof somewhat less-than-capacity diameter.

As seen in Fig. 5, also Figs, 1 and 6, cover locking formations ornotches Efix are formed at the opposite ends of the openable top coverpanel Ill. extending in from the respective end edges and in line withthe scored hinge line a for the tuck flap l5. In the fully closedcondition, noting particularly Fig. 6, these locking notches Illa: areadapted to receive the described locking pro ections E90. on theadjacent longitudinal edges of the flaps [9, thus affording a positiveinterlock for retaining both hinged cover portions H! and i5 closed.

Assuming the blank to have been glued, folded and set up to thecompleted form of Figs. 1 to 4, with the four side walls I I to I4secured adhesively or otherwise by flatwise attachment of the glue flaps20-22 against the adjacent end panels l8, the content roll R of waxpaper or other sheet in roll form is inserted, the box being open as inFigs. 1 and 2. The free tuck tabs 23 are turned in and the openablefront side cover 15 is swung inwardly to the position as in Fig. 3. Thedust flaps l9 carried by the secured end panels [8 are bent in over theadjacent ends of the roll. The other or top openable cover I0 is closeddown with its tuck flap 15 inserted inside the free longitudinal edge ofthe front cover member I5; Fig. 4. As the cover members are brought tofull closed position the locking notches I02: come opposite the adjacentlongitudinal edges ISa of the dust flaps I9 allowing the latter tospring laterally or forwardly out into the locking notches, positivelylocking the parts in closed position. The tuck tabs 23 cooperate in thisclosin and locking function, limiting down movement of the top cover itand aiding in providing rigidity and a tight closure for the severalinterrelated hinged closure elements.

The described construction further facilitates the dispensing of thecontained supply roll R as will be apparent by reference to Fig. 4.There the leading edge of the overwound roll R is indicated as turnedupwardly around the free edge of the tuck flap I8 and extendingoutwardly in the crevice between the two closed and locked front and topcover panels I0 and IS. The free edge of the front panel l5 may beconstructed or treated to serve as a cutting edge, serrated orotherwise, as y p egnation with stiffening material or by attachment ofa metal or other cutting edge. To facilitate access to the leading edgeof the sheet or strip material of the roll without opening of the boxthe top cover Hi and tuck flap it may be formed with one or morecut-scored areas or aperture-forming portions Illa, l6a, Figs. 1 and 5,for access by the thumb and forefinger of the user.

My invention is not limited to the particular embodiment thereofillustrated and described herein, and I set forth its scope in myfollowing claim.
